While this latter connection may be of any approved form ofconstruction, I prefer that seen best in Flgs. 1 and 7, as the samepermits of ready application ordet-ac'hm'ent when desired! I In thepresentin stance I have shown this connection ascomprising a plate 36secured to the back face of theseat portion in any suitable manner, thisplate having the lugs 37 between whlch other end being guided in a lug38 projecting from the plate 36, as seen clearly in Fig. 7, the outerend of thebolt having a header the like 39, a spring 40 surrounding thebolt between the lug 38 and the adjacent lug37 and bearing against acollar or the like 41 on a sleeve 42 secured to the bolt in any suitablemanner, as by a pin This spring serves to keep the bolt normallyprojected, so as to hold the link 34 in place, but

when pulledendwise against the spring, the link may be removed. Thesleeve serves, by abutting against the lug 38, to prevent entireremovalof the bolt.- It will readily be seen that this provides an easymeans for attaching or detaching the link 34 and while this isevidentthat other means may be providedforms a. convenient mode of. attachment,it

for this purpose. While thel'ower. end of the link 31' may be pivotallymounted in any suitable manner, I

find the construction shown in Fig. 6 to be desirable. As hereshown, 44is a plate secured to the base portion of the. chair and I having thevertical lugs 45 in one of which is a pointed projection 46 engaging acorresponding depression in the end of the link 31, while in the otherlug is screw threaded a screw 47 havinga pointed end 48 ensome suitablereticulated material which will permit of the passage of the airtherethrough but which will retain the dust and dirt.

I This dust bag is removably held within the cylinderin some convenientmanner. In the present instance I have shown. it as having a flange 52which rests upon the dust cap 53 which is cast to fit the curvature ofthe cylinder, -54 being a ring on the interior of the cylinder, 55 beingthe cover which bears against the flange 52 of the dust cap and securedin position by suitable means so that it may be readily detached whendesired. In the present instance I have shown the dust cover 55 asprovided with oppositely disposed lugs 56 having oppositely arrangedopenings 57, forming hooks or the'like which engage the bolts 58 whichare secured to the cylinder and providedwith thumb nuts 59,

so that when the hooked lugs 56 are engaged .with the-bolts 58 andthe-thumb nuts 59 tightened, a perfect air-tight joint is pro-' vided.Loosening of the nuts and partial revolution of the dust cover so as todisengage the lugs from the .bolts, perm1ts of removal offthe dustcover. and then the bag tion with a va'cuum cleaner head of any suit--able form of constructiom 61 1s a pipe with a suitable coupling 62 so Iit can be readily disconnected, one branch of this pipe communicatingwith the interior of the cylinder 8-, as shownat 63, and the othercommunicating, as at 64, withthe interior of the how] .17.

said pipe. r

67 is .a spring-actuated valve such as apuppet valve, seen best in Figs.3 and 4, conone sideJof the diaphragm therein, while 68 is a similar.valve controlling the outlet from 65vis a flap valve pivotal'ly mounted,as at 66, and controlling the communication at 64 between the bowl andthe trolling the outlet from the bowl 17 upon the seat is rocked,assuming the parts to be in the positionin which they are'seen in Fig.2,: downward pressure upon the seat in the direction of the arrow seenin Fig. 2, forces the diaphragm 13 inthe direction of the arrow seen insaid Fig. 2. This closes the valve 19 and opens the valve 68 and thevalve 65, creating a vacuum in the cylinder 8. As the seat is moved inthe opposite direction, the diaphragm is moved in the reverse direction,opening the valve 19 and the valve 67, closing the valve 65 and thevalve 68. The alternate movements of the seat causes, by'means of thesuction, the dust and dirt from the floor or other surface to be cleanedto be drawn into the dust bag 51. It is to be understood that thealternate opposite movements of the diaphragm automatically controls thevalves and, consequently, the suction, so that as long as the chair isbeing rocked, the vacuum cleaner will be actuated. As nothing is claimedas new in the vacuum cleaner itself and as any suitable form may beemployed and connected with the pipe 60 leading to the dust bag, it hasnot been deemed necessary to illustrate such cleaner.

From the above it will be seen that I have devised a simple, eflicientand durable form of operating means for a vacuum cleaner de-.

signed to be actuated by the movement of a rocking chair, and while thestructural embodiment of the invention as herein disclosed is what I atthe present time consider preferable, it is evident that the sameissubject to changes, variations and modifications in details,proportions of parts etc., without departing from the spirit of theinvention or sacrificing any of its advantages. I, therefore, do notintend to restrict myself to the- 1. A rocker, a cylinder supportedbeneath: the seat portion thereof, a bowl within the cylinder, adiaphragm in the bowl, a rod connected with the diaphragm, pivoted linkconnections between, the seat and base portions of the chair, apivotalconnection between said rod and'one of said links, a connection betweenthe cylinder and bowl upon one side of the diaphragm, and a valvedconnection between the bowl and cylinder upon the opposite side of thediaphragm.

2;), rocker, a cylinder supported beneath the seat portion thereof, abowl within the cylinder, a diaphragm in the bowl, a rod connected withthe diaphragm, pivoted link connections between the seat andbaseportions of the chair, a pivotal connection between said rod and one ofsaid links, a connection between the cylinder and bowl upon one side ofthe diaphragm, a valved connection between the bowl and cylinder uponthe opposite side of the diaphragm, and valve controlled communicationsbetween the atmosphere and the bowl upon opposite sides of thediaphragm.
